Description

Technical Field

[0001] This utility model relates to the field of dredging technology, and in particular to an anti-clogging conveying device for dredging projects. Background Technology

[0002] Dredging and conveying equipment is a device used for cleaning and conveying silt. It is mainly used in dredging projects in waterways such as rivers, reservoirs, ponds, and ports, as well as in some industrial sites that need to treat silt. Currently, dredging is mainly carried out using two methods: cutter suction dredging and pneumatic dredging.

[0003] A search of Chinese patent publication number "CN215669782U" reveals "a rapid suction device for river silt". The device uses a suction mechanism to insert a suction head into the silt. Driven by a suction pump, the silt in the river is quickly sucked away. When the silt enters the suction port, it passes through a magnetic protective ring, and the iron impurities contained in the silt are adsorbed on the protective ring to prevent damage to the equipment. The sucked-out silt is discharged into the hopper through a sewage pipe, thus cleaning the silt.

[0004] Based on the above search and existing technology, it was found that the above patent has certain defects. When the device is in use, the suction port of its sewage pump lacks screening for large foreign objects. Foreign objects are easily sucked into the sewage pump and can easily cause blockage inside the sewage pipe, affecting its use. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] In view of the shortcomings of the existing technology, this utility model provides an anti-clogging conveying device for dredging projects, which solves the technical problem of the inconvenience of using the existing devices.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] The anti-clogging conveying device for dredging projects includes a sludge suction and conveying device body. The circumferential surface of the sludge suction and conveying device body is provided with an inlet and an outlet, and the inlet of the sludge suction and conveying device body is provided with a feed pipe.

[0010] An anti-clogging structure is fixedly installed at the lower end of the feed pipe;

[0011] The anti-clogging structure includes a rigid pipe with a high-toughness membrane at the lower end. A screen is fixedly installed at the lower end of the high-toughness membrane to prevent foreign objects from entering the interior of the rigid pipe. The screen is circular with a diameter larger than that of the rigid pipe. A frame is provided on the circumferential surface of the screen, and connecting rods are symmetrically fixedly installed at the upper end of the frame.

[0012] Preferably: an arc-shaped fixing block assembly is fixedly installed on the circumferential surface of the rigid pipe, a ring is slidably installed on the upper end of the arc-shaped fixing block assembly, the ring is fixedly installed with a connecting rod, springs are symmetrically fixedly installed on the circumferential surface of the rigid pipe, both springs are fixedly installed with the ring, an external connector is fixedly installed on the circumferential surface of the rigid pipe, a sealed motor is embedded and fixedly installed inside the external connector, an eccentric wheel is fixedly installed on the output shaft of the sealed motor, and the eccentric wheel is adapted to the ring.

[0013] Preferably, the sludge suction and conveying device body has a discharge pipe at the discharge port, a float at the lower end of the sludge suction and conveying device body, and handles symmetrically arranged on the circumferential surface of the rigid pipe.

[0014] (III) Beneficial Effects

[0015] Firstly, by setting up an anti-clogging structure and installing a screen below the rigid pipe, the sludge sucked in through the rigid pipe can be screened first, which can prevent foreign objects from entering the feed pipe through the rigid pipe and causing blockage, thus improving construction efficiency. At the same time, by setting up a high-toughness membrane, not only can the sludge entering the feed pipe be screened through the screen, but it can also give the screen a certain range of movement, which is convenient for subsequent operations.

[0016] Secondly, by turning on the sealed motor, the eccentric wheel can rotate and push the ring, causing the spring on the ring to stretch and contract adaptively. This causes the ring to drive the screen to shake irregularly via the connecting rod, thus preventing foreign objects from clogging the screen and preventing the suction work from failing, thereby improving reliability.

[0023] This application provides an anti-clogging conveying device for dredging projects, effectively solving the technical problem of inconvenient use of existing devices. By setting an anti-clogging structure and installing a screen below the rigid pipe, the sludge sucked in through the rigid pipe can be screened first, preventing foreign objects from entering the feed pipe through the rigid pipe and causing blockage, thus improving construction efficiency. At the same time, by setting a high-toughness membrane, not only can the sludge entering the feed pipe be screened through the screen, but it can also give the screen a certain range of motion, facilitating subsequent operations. Furthermore, by activating the sealing motor, the eccentric wheel can rotate and push the ring, causing the spring on the ring to adaptively stretch and contract. This causes the ring to drive the screen to shake irregularly through the connecting rod, thereby preventing foreign objects from clogging the screen and causing the dredging work to malfunction, thus improving reliability.

[0024] Example

[0025] like Figure 1 - Figure 4 As shown, the technical solution in this application embodiment effectively solves the technical problem of inconvenience in using existing devices. The overall idea is as follows:

[0026] In view of the problems existing in the prior art, this utility model provides an anti-clogging conveying device for dredging projects, including a dredging conveying device body 11 (the dredging conveying device body 11 is the prior art, mainly composed of a dredging pump and a flange), the circumferential surface of the dredging conveying device body 11 is provided with an inlet and an outlet respectively, and the inlet of the dredging conveying device body 11 is provided with a feed pipe 12.

[0027] An anti-clogging structure is fixedly installed at the lower end of the feed pipe 12;

[0028] The anti-clogging structure includes a rigid pipe 13, a high-toughness membrane 14 at the lower end of the rigid pipe 13, and a screen 15 fixedly installed at the lower end of the high-toughness membrane 14 to prevent foreign objects from entering the interior of the rigid pipe 13. The screen 15 is circular and its diameter is larger than that of the rigid pipe 13. A frame 16 is provided on the circumferential surface of the screen 15, and connecting rods 17 are symmetrically fixedly installed at the upper end of the frame 16.

[0029] By setting an anti-clogging structure and installing a screen 15 below the rigid pipe 13, the sludge sucked in through the rigid pipe 13 can be screened by the screen 15 first, which can prevent foreign objects from entering the feed pipe 12 through the rigid pipe 13 and causing blockage, thus improving construction efficiency. At the same time, by setting a high-toughness membrane 14, not only can the sludge entering the feed pipe 12 be screened by the screen 15, but the screen 15 can also be given a certain range of movement to facilitate subsequent operations.

[0030] An arc-shaped fixing block assembly 18 is fixedly installed on the circumferential surface of the rigid pipe 13. A ring 19 is slidably installed on the upper end of the arc-shaped fixing block assembly 18. The ring 19 is fixedly installed with the connecting rod 17. Springs 21 are symmetrically fixedly installed on the circumferential surface of the rigid pipe 13. Both springs 21 are fixedly installed with the ring 19. An external connector 22 is fixedly installed on the circumferential surface of the rigid pipe 13. A sealed motor 23 is embedded and fixedly installed inside the external connector 22. An eccentric wheel 24 is fixedly installed on the output shaft of the sealed motor 23. The eccentric wheel 24 is adapted to the ring 19.

[0031] By activating the sealing motor 23, the eccentric wheel 24 can rotate and push the ring 19, causing the spring 21 on the ring 19 to stretch and contract adaptively. This causes the ring 19 to drive the screen 15 to shake irregularly via the connecting rod 17, thereby preventing foreign objects from clogging the screen 15 and causing the suction work to malfunction, thus improving reliability.

[0032] The main body 11 of the sludge suction and conveying device is provided with a discharge pipe 25 at the discharge port, a float 26 at the lower end of the main body 11 of the sludge suction and conveying device, and handles 27 symmetrically provided on the circumferential surface of the rigid pipe 13.

[0033] By setting the discharge pipe 25, the sludge sucked in by the sludge suction and conveying device body 11 can be discharged. By setting the float 26, the sludge suction and conveying device body 11 can be placed on the sludge without sinking. By setting the handle 27, it is convenient for the staff to pick up the rigid pipe 13 for operation.

[0034] Working principle:

[0035] In the first step, when using the device, the operator can first use the handle 27 to move the rigid pipe 13 to the suction area. Then, the operator can turn on the suction and conveying device body 11, so that the suction and conveying device body 11 generates suction through the feed pipe 12 and the rigid pipe 13 to suck in the sludge. At the same time, the sludge before being sucked into the rigid pipe 13 will be screened through the screen 15 to prevent debris from being sucked into the feed pipe 12 by the rigid pipe 13, which would cause the feed pipe 12 to become blocked.

[0036] The second step is that when the staff turns on the sealing motor 23, the sealing motor 23 will drive the eccentric wheel 24 to rotate, causing the eccentric wheel 24 to push the ring 19, so that the spring 21 on the ring 19 will stretch and contract adaptively, causing the ring 19 to drive the screen 15 to shake irregularly, thereby preventing some foreign objects from clogging the screen 15.

[0037] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
